Contains information needed to resolve enumerations. When resolving enums,
adjustments need to be made in two scenarios: the index for an enum symbol
might be different in the reader or writer, or the reader might not have a
symbol that was written out for the writer (which is an error, but one we can
only detect when decoding data).
These adjustments are reflected in the instance variable
adjustments. For the symbol with index i in the writer's
enum definition, adjustments[i] -- and integer -- contains the
adjustment for that symbol. If the integer is positive, then reader also has
the symbol and the integer is its index in the reader's schema. If
adjustment[i] is negative, then the reader does not have
the corresponding symbol (which is the error case).
Sometimes there's no adjustments needed: all symbols in the reader have the
same index in the reader's and writer's schema. This is a common case, and it
allows for some optimization. To signal that this is the case,
noAdjustmentsNeeded is set to true.
